### Promoted Local Ephemeral Storage Capacity Isolation to Stable

- Fix raw block mode CSI NodePublishVolume stage miss pod info ([#99069](https://github.com/kubernetes/kubernetes/pull/99069), [@phantooom](https://github.com/phantooom)) [SIG Storage]
- Fix rounding of volume storage requests ([#100100](https://github.com/kubernetes/kubernetes/pull/100100), [@maxlaverse](https://github.com/maxlaverse)) [SIG Cloud Provider and Storage]

### SIG Storage

[SIG Storage][] is responsible for storage and volume plugin components.

For the 1.8 release, SIG Storage extended the Kubernetes storage API. In addition to providing simple
volume availability, the API now enables volume resizing and snapshotting. These features are in alpha.
The SIG also focused on providing more control over storage: the ability to set requests and

- Changed feature CSIMigrationAWS to on by default. This feature requires the AWS EBS CSI driver to be installed. (#106098, @wongma7) [SIG Storage]
- Ensures that volume is deleted from the storage backend when the user tries to delete the PV object manually and the PV ReclaimPolicy is Delete. (#105773, @deepakkinni) [SIG Apps and Storage]

### Storage Capacity and Volume Expansion Are Generally Available

[Storage capacity tracking](https://github.com/kubernetes/enhancements/issues/1472)
supports exposing currently available storage capacity via [CSIStorageCapacity objects](https://kubernetes.io/docs/concepts/storage/storage-capacity/#api)
and enhances scheduling of pods that use CSI volumes with late binding.
